AMPA Regional ITS Architecture Update

Element Expanded Functional Requirements: NMDOT Signal Lab

Functional Area: Collect Traffic Surveillance
  1. The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
  2. The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.
  3. The center shall monitor, analyze, and store multimodal crossing and high occupancy vehicle (HOV) lane sensor data under remote control of the center.
  4. The center shall distribute road network conditions data (raw or processed) based on collected and analyzed traffic sensor and surveillance data to other centers.
  5. The center shall respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.
  6. The center shall maintain a database of surveillance equipment and sensors and associated data (including the roadway on which they are located, the type of data collected, and the ownership of each )
  7. The center shall support an interface with a map update provider, or other appropriate data sources, through which updates of digitized map data can be obtained and used as a background for traffic data.
Functional Area: HRI Traffic Management
  1. The center shall remotely control highway-rail intersection (HRI) equipment located in the field.
  2. The center shall accept collect highway-rail intersection (HRI) advisory or alert data from rail operations centers.
  3. The center shall collect highway-rail intersection (HRI) equipment operational status and compare against the control information sent by the center.
  4. The center shall provide the highway-rail intersection (HRI) equipment operational status to rail operations centers.
  5. The center shall collect incident information related to a highway-rail intersection (HRI), such as intersection blockages or crashes or equipment malfunctions.
  6. The center shall implement control plans to coordinate signalized intersections around highway-rail intersections (HRI), under control of center personnel, based on data from sensors and surveillance monitoring traffic conditions, incidents, equipment faults, pedestrian crossings, etc.
Functional Area: TMC Signal Control
  1. The center shall remotely control traffic signal controllers.
  2. The center shall accept notifications of pedestrian calls.
  3. The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
  4. The center shall collect traffic signal controller fault data from the field.
  5. The center shall manage (define, store and modify) control plans to coordinate signalized intersections, to be engaged at the direction of center personnel or according to a daily schedule.
  6. The center shall implement control plans to coordinate signalized intersections based on data from sensors.
  7. The center shall manage boundaries of the control sections used within the signal system.
  8. The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.
  9. The center shall implement an adaptive signal system on a series of intersections.
Functional Area: Traffic Equipment Maintenance
  1. The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
  2. The center shall collect and store CCTV surveillance system (traffic, pedestrian) operational status.
  3. The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) fault data and send to the maintenance center for repair.
  4. The center shall collect and store CCTV surveillance system (traffic, pedestrian) fault data send to the maintenance center for repair.
  5. The center shall collect environmental sensor operational status.
  6. The center shall collect environmental sensor equipment fault data and send to the maintenance center for repair.
  7. The center shall exchange data with maintenance centers concerning the reporting of faulty equipment and the schedule/status of their repair. Information exchanged includes details of new equipment faults, and clearances when the faults are cleared.
  8. The center shall support an interface with a map update provider, or other appropriate data sources, through which updates of digitized map data can be obtained and used as a background for traffic maintenance data.
